This document provides guidelines for installing an electric heat tracing system on pipes. It describes the components of a heat tracing system and outlines the installation process. Key steps include laying out the heating cable along the bottom of the pipe, allowing extra cable for valves and joints, and securing it in place with attachment tape every 12 inches. Additional cable is needed on valves, pumps, elbows and other areas with increased heat loss.
Self-regulating systems are the preferred choice for most complex pipe-tracing applications. This is due to their parallel construction, which allows them to be cut to length and spliced in the eld, and their self-regulating output, which provides more heat where it is needed.
This step-by-step design guide provides the tools necessary to design a self-regulating heat-tracing system for insulated pipes and tubing. For other applications or for design assistance, contact ISI at 407.324.7800 or www.isisales.com.

Generally, when we talk about Pipe stress analysis basics, we tend to quickly jump to Failure theories, B31.3, Caesar II, Static & Dynamic, offshore /onshore, jacketed piping etc.
Walk through Pipe stress is to ease into piping stress world with its polite introduction to curious techies, without having hold on Forces/moments/displacement equations.
Pipe Stress Analysis Basics will be taken next.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Thermal Insulation . . .
1. The need for properly installed and well-maintained
thermal insulation cannot be overemphasized. Without
insulation, heat losses are generally too high to be offset by
a conventional heat tracing system.
2. In addition to piping and in-line equipment such as pumps
and valves, all heat sinks must be properly insulated. This
includes pipe supports, hangers, flanges and, in most cases,
valve bonnets.
3. Regardless of the type or thickness of insulation used, a
protective barrier should be installed. This protects the
insulation from moisture intrusion, physical damage and
helps ensure the proper performance of the heat tracing
system. Seal around all penetrations through the thermal
insulation.
4. After the installation of the thermal insulation and weather
barrier but BEFORE ENERGIZING THE HEATING CIRCUIT,
the megohmmeter test should be repeated. This should call
attention to any damage to the heating cable that may have
occurred during the insulation installation. (Record 3 on
Cable Testing Report)
5. Apply caution labels to insulation weather barrier at required
intervals along pipe
Final Inspection and Documentation . . .
1. It is recommended that the circuit be temporarily energized
so that the volts, amps, pipe temperature and ambient
temperature may be recorded. This information may be of
value for future reference and should be maintained for the
historical operating data log (Record 4 on Cable Testing
Report).
2. Stabilized design can be used for self-regulating heating
cables to assign a lower T-class through the use of the
Thermon CompuTrace software or Thermon Engineering.
3. Stabilized design can be used for power-limiting and con-stant
watt heating cables without a limiting device to deter-mine
the T-class through the use of the Thermon Compu-
Trace software or Thermon Engineering.
4. A sample historical operating data log form is included in
the Electric Heat Tracing Maintenance and Troubleshooting
Guide, Thermon Form TEP0066).
Final Connections . . .
1. Follow the circuit fabrication instructions for the specific
cable type. Power connection and end-of-circuit termina-tion
kits are designed for each type of cable; substitutions
should not be made.
2. For ambient controlled power, the heating circuit should be
connected directly to the switched power feed wiring.

3. For pipewall sensing thermostatic control, the heating circuit
is to be connected in series with the control contacts as
shown below. The pipewall sensing thermostat may require
more than one support point.
The National Electric Code and Canadian Electrical
Code require ground-fault protection be provided
for branch circuits supplying electric heat tracing.

8. Cable Testing Report
1. Refer to Thermon Installation Procedures, FORM PN 50207, for general installation procedures, requirements and guidelines.
2. Upon receiving heating cable, check the cable to make sure the proper type and output have been received. All flexible cables
have the catalog number, voltage rating and watt output printed on the outer jacket.
3. Visually inspect cable for any damage incurred during shipment. The heating cable should be tested to ensure electrical integrity
with at least a 500 Vdc megger between the heating cable bus wires and the heating cable metallic braid.
IEEE 515 recommends that the test voltage for polymer insulated heating cables be 2500 Vdc. Minimum resistance should be
20 megohms. (Record 1 on Cable Testing Report.)
A. Connect the positive lead of the megger to the cable bus wires.
B. Connect the negative lead of the megger to the metallic braid.
C. Energize the megger and record the reading. Readings between
20 megohms and infinity are acceptable. Readings below 20
megohms may mean the electrical insulation has been dam-aged.
Recheck the heating cable for physical damage between
the braid and the heating element; small cuts or scuffmarks on
the outer jacket will not affect the megger reading unless there was actual penetration through the braid and dielectric insula-tion
jacket.
4. Once the installation is complete, but prior to installation of thermal insulation, recheck the heating cable with at least a 500 Vdc
megger between the heating cable bus wires and the heating cable metallic braid. IEEE 515 recommends that the test voltage
for polymer insulated heating cables be 2500 Vdc should be 20 megohms. (Record 2 on Cable Testing Report.)
5. After the thermal insulation is installed, the megohmmeter test should be repeated. Minimum resistance should be 5 megohms.
(Record 3 on Cable Testing Report.)
6. After the thermal insulation is installed and power supply is completed, record the panel and circuit breaker information. Ensure
all junction boxes, temperature controllers, cable glands, etc. are properly secured. Set the temperature controller (if appli-cable)
to the manual setting and apply rated voltage to the heat tracing circuit(s) for 5 minutes. Record the ambient temperature,
measure and record the circuit(s) voltage and current. (Record 4 on Cable Testing Report.)
NOTE: To ensure the heating cable warranty is maintained through installation, the testing outlined on
this sheet must be completed on the installed heating cables, and the test results recorded and
mailed/faxed to:
